Hello everybody! As many others users, I get a black screen when I try to switch on the nvidia card. I am just a user, therefore I just give my feedback.
I use nvidia-prime and the nvidia drivers coming from the ppa xorg-edgers ppa. I use also prime-indicator for quickly switch between the nvidia (GTX880M) and the intel card and my login manager is lightdm. First comment, for me the black screen issue doesn't comes from the driver but of nvidia-prime. My first suggestion to solve the black screen. Using the the root privilege edit the file /sbin/prime-offload and just replace the first line #!/bin/sh by #!/bin/bash. Now, you can use the command: prime-select nvidia (or intel) and reboot your laptop. Normally, now you can switch between the two cards but the quick switch of "prime-indicator" doesn't work. For the next step, I don't have a real solution but just a workaround: With the root privilege edit the files /usr/lib/primeindicator/igpuon and /usr/lib/primeindicator/dgpuon and just before "sync" insert this line: service lightdm restart So you get this for the file igpuon: prime-select intel service lightdm restart sync And you get this for the file igpuon: prime-select nvidia service lightdm restart sync I hope that this feed-back will be helpful to other people. ++ Kirby -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-331 in Ubuntu. https://bugs.launchpad.net/bugs/1362848 Title: ubuntu 14.04 after install nvidia binary driver 331.89 black screen and freeze Status in nvidia-graphics-drivers-331 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-340 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-346 package in Ubuntu: Confirmed Bug description: I'm using Ubuntu 14.04 64bit, after install nvidia binary driver 331.89 from Additional Drivers application then reboot, it shows black screen, no login window, I even can't use ctrl+alt+F2 to switch to text mode, then I reboot and go to recovery mode, use 'prime-select intel' to switch to intel GPU and reboot, everything is fine, but as soon as I switch to nvidia GPU, still same issue.
